Only moved in a few months ago and our balcony roof is leaking though to the bedroom below. Its currently tiles over felt then boards and wood joists. Its about 3mx4.5m.
We're starting to get quotes for replacements but we're hearing conflicting opinions on what is most suitable for the flooring...so over to you: what is the most suitable type of flooring for a balcony roof that is going to be walked over? Tiles over felt, fibre glass, some sort of membrane system?
